Comfort & fit
68

Light shell; one reviewer found pressure in long sessions

Each part is rated on one scale for every earbud and headphone, from lab test measurements where they exist, what reviewers found, specs and owner reports. It rates the product itself, not how good it is for the price.

Pros

  • Natural, textured mids and tidy treble
  • Bass with real rumble, more via a switch
  • Foam tips comfortable for hours
  • Good detachable cable
  • Inline mic fine for calls
  • Well-judged Harman tuning with clean bass and sub-bass rumble
  • Clean mids

Cons

  • Switches are fiddly and need the tool
  • Clear plastic and cable may yellow
  • No case
  • Tuned for listeners, not bass lovers
  • Treble rolls off early
  • Average stage and imaging
  • Build is basic; KZ QC means buy from authorised sellers
  • MySmartPrice

    A great cheap entry into hi-fi with natural mids and handy switches. Indian review; tested the Improved Bass variant.

  • ChiFi WireJun 2026

    The Harman version is the one to buy: KZ's most refined tuning yet, though not a technical champion.

  • ShutterGrooveApr 2026

    A practical budget set for games and daily listening; less suited to fans of natural vocals or long sessions. Score is their sound-quality mark.

  • Head-fi (suicideup, via KeepHiFi)Jan 2026

    KZ's best yet and a strong budget neutral pick; the switches add little.
